Hello,

we do not use this hardware in our environment, but I'd just like to give you a little insight into this issue.

The PSOD was caused within a Translation lookaside buffer - a certain subset of CPU's microcode to speed up the translation of Physical to Virtual address space. The BIOS upgrade comes into play when there is some sort of issue reported with the CPU's microcode. It seems there is a miscommunication somewhere along the bus or within the CPU itself, and then the host crashes to maintain data integrity. This was a purely code-oriented issue and nothing to fear hardware-wise. Try updating the BIOS on your hosts and give it a test drive Smiley Happy
